Leonardo DiCaprio Sets Off To Save The World In 'Before The Flood' Trailer

Back in 2007, Leonardo DiCaprio released a documentary film that cast an in-depth look at the state of our vulnerable Earth. In the process, The 11th Hour not only made us stand to attention to the issues at hand, but also outlined the actor as one of the most passionate stars campaigning for environmental change in Hollywood.

These days, it's been almost ten years since Leo first brought together expert assessments, shocking images and astonishing statistics in attempts to make humankind realize just how much critical damage we have been doing to our planet. And now, it appears that DiCaprio is trying to bring environmental awareness to the masses once again in new documentary Before the Flood.

Leonardo DiCaprio's 'Before The Flood' Is His Most Ambitious Project To Date

Directed by Fisher Stevens and produced by Martin Scorsese, the frightening expose sees Leo shine a light on the catastrophic effects of global warming, and perhaps most importantly, whether we can reverse the tremendous destruction occurring.

In the newly-released trailer for Before the Flood, Leonardo DiCaprio travels all over the world speaking with renowned scientists, politicians (including Barack Obama and Secretary of State John Kerry), religious leaders and ordinary people combating the pollution, dwindling resources and natural disasters occurring in various parts of the world as a result of fossil fuel abuse.

In fact, such is Leo's dedication to the cause that the actor even comes head-to-head with a polar bear in a frozen wasteland — you'll be happy to know that this time he fares better than the grisly confrontation in The Revenant. Watch the trailer below:

'Climate change is the most critical and urgent problem facing our world today'

All in all, Before the Flood is undisputedly Leonardo DiCaprio's most ambitious environmental project to date and is currently causing a stir ahead of its October 21 release date. On Tuesday, DiCaprio spoke at length about the goals that the documentary aimed to achieve within the realms of environment conservation, saying:

"Climate change is the most critical and urgent problem facing our world today, and it must be a top issue for voters this Election Day. Fisher and I set out to make a film that not only educates people about the challenges we face if we fail to act, but one which also shows the solutions we can implement if we can find the political will to do so."

Then, directly addressing the baffling ignorance of those who refuse to believe that climate change is occurring, Leo added:

"We need leaders not only in the United States, but across the globe, who believe in the science of climate change and who have the courage to take a stand for our planet. Bringing this film to college campuses is a key component to engaging young voters to hold our leaders accountable."

Ultimately, Leonardo DiCaprio's environmental influence refuses to go unnoticed and he continues to educate and inspire millions of people worldwide with his decades-long commitment to the cause. While we wait patiently for the release of Before the Flood, familiarize yourself with some other ways in which he's tried to make an impact on saving our planet in the last couple of years alone:

1. The Leonardo DiCaprio Foundation

In 1998, at the height of dizzying Titanic fame, Leonardo DiCaprio began a charity. Its mission was to protect endangered eco-systems, to restore balance and to ensure that people were being educated about the struggling health of our vulnerable world.

To this day, The Leonardo DiCaprio Foundation continues to support projects all around the globe, working with teams of conservationists to protect oceans, landscapes and thousands of endangered creatures suffering due to man's neglectful attitude toward the planet. In 2015 alone, the LDF worked to protect marine life, restore degraded coasts in Africa, conserve protected indigenous lands in the Amazon, save gorilla ecosystems in Africa's Virunga National Park and expand elephant sanctuaries. All incredible feats that simply cannot be praised enough.

2. Leonardo DiCaprio's Oscars Speech

All eyes were on Leo as the Academy Awards swung around in 2016. After decades of stellar contributions to the movie industry, we could all finally breathe a sigh of relief when DiCaprio finally ascended that podium to receive his Best Actor award for The Revenant.

After thanking a long list of people for helping him get to where is today, before breezing off the stage to celebrate, Leonardo DiCaprio took the time to speak about climate change. Here's the transcript:

"Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating. We need to support leaders around the world who do not speak for the big polluters, but who speak for all of humanity, for the indigenous people of the world, for the billions and billions of underprivileged people out there who would be most affected by this. For our children’s children, and for those people out there whose voices have been drowned out by the politics of greed. I thank you all for this amazing award tonight. Let us not take this planet for granted. I do not take tonight for granted."

3. His Impassioned Address To The United Nations On Earth Day

In 2014, the United Nations named Leonardo DiCaprio its UN Messenger of Peace with a special focus on climate change, a monumental role that he has taken up whole-heartedly.

His most recent contribution fell on Earth Day last April 2016, when the actor gave a rousing speech in front of hundreds of world leaders and urged them that they were the "last best hope" to save our planet from global warming. Among some of the hard-hitting words he spoke, he reiterated the need to leave fossil fuels firmly in the ground:

"Our planet cannot be saved unless we leave fossil fuels in the ground where they belong. Now is the time for bold, unprecedented action. My friends, look at the delegates around you, it is time to ask each other, which side of history will you be on? No more talk, no more excuses, no more 10-year studies."

With this and Leonardo DiCaprio's most recent appeal in Before the Flood, let's hope the world finally starts listening.

National Geographic will debut Before the Flood in limited theaters on October 21, before premiering the documentary on TV the following week on October 30, 2016.
